Answer:
It has producer-consumer relationship with sugar-maple trees because it gets food from the trees.
Explanation:
The mourning bird is primarily a seed eater and not an insect eater. Since it is a seed eater, it will directly from the sugar-maple tree which is the producer.
In an ecosystem, the producers are plants which can trap energy directly from the sun during photosynthesis. This energy is passed on to the consumers.
Hence, the mourning bird has producer-consumer relationship with sugar-maple trees because it gets food from the trees.
Answer:
B)154 J
Explanation:
Mass of bowling ball=m=6.55kg
Height of bowling ball from ground=h=2.4m
Acceleration due to gravity=
We know that
Potential energy=mgh
Where m=Mass of object
g=Acceleration due to gravity
h=Height of object from ground
Substitute the values then we get
Potential energy=
Hence, the increase in the ball's potential energy=154J
the greater the <u>mass</u> of an object the more force is needed to cause acceleration
A. At the top. At this point, the child is highest, and they are not moving. Their potential energy is much greater.
Answer:
Explanation:
River is 7.5 m wide . Time taken by it cover this displacement
= displacement / velocity
= 7.5 / 0.4
= 18.75 s
During this period , swimmer will have a displacement of 30 m due to velocity of river water .
Displacement of 30 m downstream will be due to flow of river .
velocity of water flow = displacement / time
= 30 / 18.75
= 1.6 m /s
